****** Breeding Season ******
by 5bluetriangles
Summary
     Morty gets his first heat and Rick finds him.
Notes
     I found this in my folder I put my stories in on my computer and
     thought I might as well post it here now that I have an account! Most
     of my stories will probably be kinda quick and dirty like this cuz it
     takes FOREVER for me to write but yeah.
Morty’s school didn’t give the best sex ed.
They told the omegas that each month when their cycle began; they would go into
heat and that they would have to be careful for alphas because they would want
to breed them. They said how they would get hot and need to breed but not much
else.
Which is why when Morty’s first heat hit; he didn’t know what it was.
He woke up hot and sweaty with aches and pains and thought he was just getting
sick. He was slick between his cheeks too but didn’t think much of it. It had
happened a couple times before and he just put a slick pad in his underwear.
His dad had given them to him, seeing as he was an omega too and said that he
would need them at some point.
He washed his face after checking his temperature.
A bad fever.
He walked downstairs carefully, putting his wet underwear and pajama pants in
the washer before getting some water from the kitchen to quench his thirst. No
one was home, so he took over the tv as he cuddled up on the couch. He wanted
to be under a blanket but it was obviously too hot so he just got as
comfortable as he could and leaned against the arm as he flicked through the
channels.
Despite how bad he was feeling; he made sure to lift his head up every once and
a while to drink water. He knew better now because last time he got sick; he
didn’t drink enough and everything got worse.
When the door opened; he didn’t budge, not interested in who had come home. It
was the garage kitchen door so he guessed it was Rick.
It was.
Rick could smell the fertility in the air and in his curiosity; followed the
scent to find the source. It was too fresh and new and sweet to be Jerry, that
was for sure.
He came to find Morty, looking utterly miserable on the couch and his eyes
widened. Of course, he knew that it would be sooner or later but Morty wasn’t
hiding away in his room like the alpha thought he would be. The boy had to know
that he shouldn’t be out here, right?
“Heeyyy there, Morty,” Rick said, stepping over and doing his best not to keep
smelling the omega. “How are you uh—how are you feeling?”
“I—I think I’m getting sick. I have a—a fever.” Morty mumbled and his mind was
drawn to Rick’s scent. He never really noticed it before. Of course, it was
there; like everybody else’s but it smelled so enticing right now.
The man smelled amazing. Like spice and the hint of cologne and most important
of all; he smelled like alpha. Morty had smelled alphas plenty -Rick the most-
and while they smelled good; they didn’t smell this good. Alphas, and most
importantly Rick, never affected him like this. Maybe now that he presented;
his senses got more sensitive when he was sick.
Rick licked lips, smelling the air somewhat indiscreetly and breathing in
Morty’s scent. Definitely heat.
Morty was in too much of a daze to notice as he was dipping in and out of heady
arousal from the other scent in the room, slick still dripping out. This
certainly wasn’t normal for being sick. He was too horny to be sick.
Rick hummed out a gentle growl without knowing, muscles tense as he watched the
omega wiggling slightly on the couch. He could smell the slick, the sense-
achingly sweet, familiar scent and he found himself stepping closer. Morty
looked up at him, eyes glassy, lips parted and he leaned down, picking the boy
up.
Morty squeaked, clinging on tight as Rick sat down in his spot and he did his
best to settle down in the man’s lap. He was so wet and Rick smelled so good
and he honestly couldn’t resist the attention as the man brought him close.
“Fuck baby, y-you smell good,” Rick murmured, pressing his nose in Morty’s
neck. “Yy-you’re not getting sick.”
“N-no?” Morty breathed, unable to help himself as he ground down on Rick’s
thigh since he was straddling it.
“Uh-uh. You’re going into—into heat.” Rick brushed his lips against Morty’s
throat and lifted his leg somewhat to help give the boy the friction he was
seeking.
Morty tensed, heart jumping into his throat at that fact.
He should have realized.
But before panic could set in; Rick squeezed Morty closer to him possessively
and cooed for him to stay calm. “I’m gonna take real—real good care of you baby
boy. Don’t wuh—don’t worry.”
“Are you—are you going to breed me?” Morty whimpered, still not very aware of
himself or the fact that he was humping Rick’s leg. All he knew was the
pleasure, the desperation, Rick’s scent, and everywhere his body was being
touched. His skin burned and tingled where Rick was kissing his neck, where the
man was holding him tight and between his legs. His hole was the worst. It
ached, felt loose and sloppy and even though he had never had anything in there
before; he sure as hell wanted something in there now.
“Yeah baby,” Rick panted into the omega’s neck, rocking his hips up.
“Gonna—gonna breed you nice and hard.”
Rick’s words made blood pound in Morty’s ears at the arousal but he was scared
too. If Rick bred him, they’d be mates, right? Would their parents be mad? He’d
get pregnant, right? How did breeding even work? Would it hurt?
Morty had just worn sweatpants for bottoms and Rick tugged them along with the
boxer briefs over the boy’s bottom, groaning low in his throat. Of course, now
that there was nothing blocking the scent of Morty’s slick; the smell was
nearly overwhelming and Rick’s nostrils flared as he breathed it in.
Morty was whining as he weakly maneuvered to help Rick take off his pants and
underwear and chewed at his lower lip painfully to try to ignore his
desperation. His legs ached as he kicked the articles of clothing to the floor
and he yelped slightly, grabbing onto Rick as the alpha reached down to spread
his cheeks.
Rick growled soft and low in his throat as he slipped two fingers between
Morty’s cheeks and pressed them inside him. Despite the boy being literally
dripping wet; starting with two fingers was a bold move and Morty squealed as
they nudged into him.
“Shh baby,” Rick cooed as Morty held tight onto him as though he was drowning
and squeezed around his fingers. “You gotta relax.”
“It’s big,” Morty whimpered through grit teeth.
“It’s only two fingers. You can take it, baby.” Rick murmured, pressing kisses
to Morty’s neck as the boy whined at the movement of his fingers. He was
honestly being a little rough; not patient enough to wait for longer than
needed but Morty, being the little trooper that he was, was taking it like he
was told.
Morty was wiggling slightly in Rick’s lap, both trying to get away and get more
of the man’s fingers. His body was still burning with desire but Rick’s fingers
just didn’t fit comfortably in him and he was scared of what the alpha’s cock
would be like. He was focusing on his breathing, trying to calm down and relax
like Rick was telling him to, but his mind was all over the place and
completely out of it at the same time. He recognized how he was feeling by the
way he felt when he had to take prescription medication. Out of reality and
perfectly aware all at once.
Rick thrust his fingers in and out of Morty’s hole, letting the slick do its
job and help him open the boy up. This was Morty’s first heat and he
unfortunately couldn’t just force his cock in there. Had to stretch him a bit
so he wouldn’t tear anything for god’s sake.
Morty’s heat won over his fear and he couldn’t help but push back on Rick’s
fingers, feeling like he was going to die from the mix of pleasure and pain.
“That’s a good boy,” Rick breathed, pressing his fingers deeper. The trick to
opening somebody up was motion and now that he had done that for a while; he
could stretch the boy more and do it again. He was still rushing it though,
eager for his knot to lock them together.
Morty was babbling nonsense, not true words at all but Rick was far too
distracted to ask the boy what he was trying to say. What Morty was thinking
was how much he hurt, and how good he felt. It was all too much but he was
desperate for more. He needed more or… He didn’t know.
Rick pushed a third finger in, making Morty whimper and claw at him but thrust
them in and out hard as Morty panted. He got Morty used to that but skipped a
forth in favor of pushing his trousers and boxers down just enough to let his
cock bob free.
Morty’s eyes widened at it. His own was around four inches long, big for an
omega, but Rick’s was around six and while his was a nice thickness; Rick’s was
thicker. “Thuh-that isn’t gonna fit, Rick.”
“It’ll fit.”
Morty whimpered uncertainly as Rick grabbed onto his hips, pulling him forward
to be over his cock.
Rick held his cock, positioning it so the head was pressed against Morty’s hole
and used his other hand to gently tug on the boy’s hips. “Come on Morty, sit
down.”
“I—I don’t know if I can,” Morty whined.
“Baby, I gotta breed you, yeah?”
Morty didn’t know if he could take it but his body and mind was screaming at
him so he nodded.
“Then sit. Or I can just pull you down,” Rick offered, he had thought Morty
would want to do it himself.
Morty’s hands were trembling and he whimpered “You do it.”
Rick nodded, squeezing Morty’s hip with one hand and tugging him down.
Morty was hesitant but let himself be moved and gasped hard as the head of
Rick’s cock nudged itself inside him. He was shaking, whole body burning so
much worse than earlier and while the stretch hurt; it was making him feel so
good.
Rick let go of his cock once the whole head was inside and brought his hand up
to grab onto Morty’s scruff hard, making the boy’s gasps for air dissolve into
placated whines. “Shh baby,” he murmured, leaning in to mouth at the omega’s
shoulder but kept pulling him down onto his cock.
The grip on his scruff numbed Morty’s mind, rendering him somewhat limp which
helped Rick force his cock inside him and he was panting through his parted
lips, eyes dull but glossy.
Rick was breathing hard through his nose as he tried to give Morty time to
adjust by going slow, he wasn’t heartless. Plus, breeding was quick and just
fucking him now wouldn’t give him much time before he had to take his knot.
“You’re doing good baby, just a bit more,” he assured, and it was true; Morty’s
slick was making the boy’s hole pull him in and there only around two inches
left.
Morty groaned, unable to talk with his scuff being grabbed like this and having
to take Rick’s cock at the same time.
Once he was fully seated inside Morty; Rick let go of the boy’s scruff to hold
both of his hips and pull him up.
Morty sobbed, burying his face in Rick’s neck as the man pulled him back down
and he clung to him.
Rick growled, pulling Morty back up and thrusting his hips.
Morty whimpered, lifting his shoulders as Rick started to actually fuck him.
The man’s cock was making his ass ache from being too big but god, he felt so
amazing. He wanted to scream, wanted to kick his legs but couldn’t do either
and instead clawed at Rick desperately.
“Fuck, baby,” Rick groaned, pulling at Morty’s hips in time with his thrusts.
The boy felt absolutely amazing wrapped around his cock and he couldn’t help
but fuck him hard, seething through grit teeth.
“Ohhh,” Morty sobbed, cock aching at how good he felt and the friction of being
fucked like this was driving him crazy but he couldn’t do anything about it.
“Rick I—I’m gonna cum—!” he choked out, shaky hand reaching down to grasp his
cock.
“Mmn,” Rick moaned, hips stuttering. He was close too. Omega pheromones made it
difficult to last very long; better for getting the omega pregnant.
Morty came first with a gasp and a cry, squeezing hard around Rick’s cock and
shaking. Bursts of light clouded his vision behind his eyelids and he whined as
his orgasm wracked his body.
“That’s right baby, there you go,” Rick hissed and with a few more hard
thrusts, his knot started swelling. He didn’t stop though, racing for his own
release and fucked up into Morty wildly, uncoordinated.
But Morty certainly didn’t expect Rick’s knot, didn’t know what it was and
jolted upward. “Aah! Rick, what—”
“Stay still,” Rick growled, pulling Morty’s hips down hard before his still
growing knot could come out. All this would be for nothing if he couldn’t tie
the boy.
“Rick wait! What—something—”
Rick ignored Morty’s fearful babbling, instead paying attention to how good it
felt to tie somebody again. He’d be pretty sore after, but god, breeding omegas
was definitely worthwhile.
Morty hiccuped, tears running down his cheeks. It didn’t hurt very bad but he
was pretty frightened of course, especially when Rick was no longer able to
thrust in and out. “It’s stuck! Rick, it’s stuck!”
Rick groaned as he came, bucking his hips despite it not serving him any favors
as he pumped his cum into Morty.
Morty was still crying, whole body trembling as he weakly tried to lift himself
up to get Rick’s knot out since the man wasn’t clinging to him so hard anymore
but of course it wasn’t even close to coming out; it was stuck tight. Morty
whined and sniffled at the pain of being tugged at and Rick, too, made a noise
of discomfort. “Rick, take it out,” he sobbed, hiccuping.
“Can’t baby, we’re tied,” Rick panted. While his initial orgasm had passed; the
afterglow would last about as long as his knot did and he let himself relax
into the couch, tired out.
“Tied?” Morty sniffled, wiping at his eyes.
“Yeah, my knot swelled and got stuck, numbnuts. That’s what’s supposed to
happen.”
“Yuh-your knot?”
“I thought you had sex ed in school, kid.”
“I—I did.”
“And they didn’t tell you anything about how breeding actually works?”
“N-no…”
Rick groaned, letting his head fall against the back of the couch. “Alright.
Christ. I’ll tell you how it works while we wait.”
“Wait? For what? Huh-how long does this take?” Morty whimpered, weakly lifting
his shirt to wipe at his wet face.
“Like, forty minutes or so.”
Morty’s heart dropped. “I…I don’t know if I can't tuh-take this that long.” He
was sore and shaky and his ass ached even worse with Rick’s knot swollen at
full size.
“Well, i-i-it’ll hurt both of us if we try to take it out—out now.”
Morty sighed, gingerly leaning forward to cuddle up against Rick’s chest and
trying not to think about how he was definitely going to be pregnant after
this. Maybe it wouldn’t be so bad, Rick was a good alpha. But before he could
ask the man about it; he heard the front door open. He jolted despite how tired
out he was and looked over the back of the couch to see Summer turned away from
him, shifting bags of groceries in her hands to close the door.
“Jesus, dad, is that…” she trailed off when she turned around and saw Rick and
Morty on the couch.
Unlike Morty, Rick didn’t care and relaxed even further into the couch as the
boy just tensed up even more.
Summer was obviously surprised because while incest wasn’t illegal; it was
pretty frowned upon and she didn’t expect Rick to breed Morty even when the boy
presented. She stood there frozen for a few brief moments before deciding that
it wasn’t worth being upset about and just looked away, wrinkling her nose as
she headed to the kitchen. “Gross you two. Did you have to do it in the living
room? Now I have to look at you.” She waved the air around, “You stunk up the
whole house. We’re gonna have to like, burn that couch. I like that couch, you
know.”
“Eh.” Rick grunted, reaching up to give Morty a few pets before grabbing onto
the boy’s scruff again so he would calm down. “Grab me the remote, will you?
We’re kind of—of grounded here.”
“No way. It’s your fault you didn’t think ahead.” Summer called from the
kitchen as she pulled out groceries to put them away.
“Fuck you.” Rick replied half-heartedly, petting Morty’s belly with his free
hand as he continued to pump his cum into the boy. He let go of Morty’s scuff
so the boy could cuddle up to his chest again and pet his messy curls. “How
‘bout you try to get some rest, y-yeah?” he murmured.
“Uhm, yeah, o-okay,” Morty nodded gently, closing his eyes and letting Rick’s
scent calm him down.
Yeah, this wasn’t so bad.
